To all whom it may concern:

Be it known that l, CARL citizen of the of Syracuse, in the county of State of New H. BrssEnL, a United States,

York, have invented a certain new and useful Operating Mechanism for Inclosed Push-Button Switches, the following is a This invention of which speciication. v has for its object. a particularly simple and etiicient switch operating mechanism for operating standard switches, as push button located in an having a .cove

and weather tight,

switches which are electrical conduit outlet box r for rendering the box steam erable from the outside of the box. The 1nvention consis ts in the novel features and in the combinations andl constructions hereinafter set forth and cla1med.

ginal flange on the cover and threading into internal flanges 7 on the box.

The switch operating mechanism, as here shown, comprises a rock shaft 8 journaled in bearings in the cover 5 and extending tothe outside of the cover, a rocker member 9 movable with the rock shaft 8 and also having a yielding movement relatively thereto, the rocker member 9 having means as bearings 10, 11 on opposite sides of its axis for pressbuttons 3 and 4 respectively. As here shown, the rocker member is mounted upon an'arm 12 carried by the rock shat 8 and rockable therewith, and the rocker member also Ahas guides as slots 13 slidable on the shaft 8. the shaft being formed with diametrically opposite flat sides 141engaging the walls of the slots 13. The arm 12 is also formed with a similar slot-15 for engaging said flat sides 14.

The movement of the rocker member radially relatively to the shaft is resisted by a spring 16 encircling the arm 12 and pressing at its upper end against a shoulder 17 on the upper end of the arm and vat its lower end againstthe top of rl`he rock shaft is operated by suitable handles 18 extending in opposite directions therefrom, and mounted on the end of the rock shaft located outside of the casing.

lin operation, when the cover is placed on the box. housing'the snap switch, the bearings 10 and 11 engage respectively with the tops of the buttons 3, 4 and the shaft is rocked by means of the handles 18 so that as to position the rocker member in accordance with the positions or elevations ofthe push buttons 3, 4.

Assuming that the switch is off and it is desired to shift the switch to on position. the operating member 18 bearing the word On is depressed` thus roc-king the shaft 8 to the ri ht from its position shown in Fig. 1, causing the bearing member to press downwardly on the push button 4 and during the movement of the rock shaft the spring 16 permits the rocker member 9 to yield outwardly until the tension of the spring of the switch base 2 is overcome so that the push button 4 is yieldingly depressed by the rocker 9,

Then the push button 4 depresses the rocker member follows and assumes the position opposite to that shown in Fig. 1. At the same time the push button 3 is elevated.

4. A switch operating mechanism comprising a rock shaft, an arm extending radially from the rock shaft, a rocker mounted on the arm, and movable radially relatively to the axis of the shaft, and a spring acting on said member to resist radial movement thereof, and means for rocking the shaft, substantially as and for the purpose 5. A. switch operating mechanism comprising a rock shaft, an arm extending radially from the rock shaft, a rocker slidably mounted on the arm and having means located on opposite sides of the shaft for engaging the switch actuating elements, said rocker being movable radially on the arm, said arm having a shoulder spaced apart from the rocker, and a spring encircling the arm and interposed between the shoulder on the arm and the rocker member, sub-- 'I z. stantially as and for the purpose specified.

6. A switch operating mechanism comprising a rocker member, said rocker member being also yieldingly movable relatively to its axis, aspring acting on the rocker member to resist such movement, and means for rocking said member, substantially as and for the purpose set forth.

Lacasse 7. The combination with la snap switch having a pair of push buttons, for operating the switch to on and olf positions, of an operating mechanism comprising means yieldingly coactingwith the push buttons alternately to operate the same, substantially as and for the purpose described.

8. The combination with a snap switch having a pair of push buttons for shifting the switch mechanism to on'and off positions; of an operating mechanism comprising a rocker having means on opposite sides of its axis for engaging the push but-v tons, the rocker being yieldingly movable radially relatively to its axis, springs for resisting radial movement of the rocker, and means for operating the rocker, substantially as and for the purpose set forth.

9. rlhe combination with a snap switch having a pair of push buttons for shiftin the switch mechanism thereof tofon anil o positions; of an operating mechanism for the push buttons comprising a rock shaft, a rocker mounted on the arm to rock therewith and move relatively thereto, and

`a spring acting on the rocker to resist relative movement of the rocker and said shaft, and means for operating the shaft, substantially as and for the purpose described.

10. The combination of albox, a switch mounted in the box and including a movable operating element, a cover for the box, and

means carried by the cover to actuate the operating element, said means including a yieldable member coacting directly with said element, substantially as and for the purpose specified.

11. The combination of a box, a two-button snap switch mounted in *the box, a cover for the box and mechanism carried by the cover to operate the switch. said mechanism comprising a yieldingly mounted rocker coacting on opposite sides of its axis with the push buttons, substantially as and for the purpose described.

12. The combination with a. snap switch having push buttons arranged side by side, of switch operating mechanism comprising a support mountable on the switch, a rock shaft liournalled in the support, a rocker arm on said shaft and having means onv opposite sides of the shaft for coacting with the heads of the push buttons 'and means for rocking the shaft, substantially as and for the purpose described.
